To all whom it may concern."

Be'it: known thatwe, LOUIS G. MILLER and EDWARD 0. Lone, both .citi'zens'of theUnited States-,and bothresiding in' theborough of Westmont, in the county of. Cambria :and State: of Pennsylvania, have invented certain new and useful 1 Improvements in Can Doors; andwe do hereby declare the following to be. a full, clear, and. exact description of the invention such as will enable others skilled inlthemarttofl whichit appertains to makeand userthe same: a

Our invention relates to drop doorsfor railroad. freight? carsJ and particularly to those of the: hopper or. hopper gondola typ Our invention consists generally in constructing a door adaptedito close or. open a pair.ofhoppersyoneon either side of the centersill of. the .car, the necessity for this I arising particularly from the fact that the hoppers cannot pass-through the center sill,

as; the silla must be. continuous throughout the car" length and: 'in order to provide the greatest IIIUIIHGIAOIELOPQ'HlDgS, most hoppers the icenter sill. Heretoforethese; doors have been made separatelyifo'r each hopperand havetbeen connected? together by: means of what is known as door :spreaders. of various construction. As.oppo sedlto this, ,we make our. door of one piece, one end being adapted to! closeor open one of the-hoppers-and, the otherrend adapted to close; oropen the companiorr hopper. We. preferably. make the door narrower: atits middle portion just below the center sil1,-,as-no closure is requ-irediatthat placeand we therefore save material, besides making the central portion of the doorsomewhat fiexibleso that it may twist slightly, if necessary, to insure tight closing. against each ofthe hopper plates. Wemay also apply atruss structure to the dqor adapted to stifi'enit,particularly at its-narrow portion and where the pull of-the operating nnechanism is applied, so that it may bexdrawnup tightlyagain'st the hopper without-unduedeflections, or the stifi'ening member may be made integral with the door. Having thus given a general description of our inventionwe will n0w ,1inorder. to

make the-matter. more clear, refer to the acco'mpanyingiv two sheets of drawings in which like characters of referencerindicate like parts l Y Figure-.1 is;- a 1- vertical longitudinal seci n a of te Patent Patenteolflct22, rare. Application filed May 4, 1918. Serial Ho. 232,668. I

Referring now to thecharacters of reference on thedrawings:

1 indicates the car in general, 2 the side hopper sheets thereof, the lower edges of which are: adapted to contact with thedoor and form closures together with similar hopper sheets extending on the other sides .of thehopper to complete the closure. 3 is the central ridge of thecar formed, as shown, of a plate bent angularly'to cover the center sill and door operating mechanism, 4 indicates the door rigging in general, 5 the connecting links thereof, 6 are clevis bolts secured to the doors and connected with the links aforesaid. As illustrated in Figs. 1 to 5 inclusive, 7 indicates the car door in gen- .eral, 8 an opening between the two portions thereof, the door being provided with an integral downwardly extending flange 9, ex-

tending around all the edges thereof, 10 is a posed between it and thedoor, theends of the spreader being secured or riveted to the door plate, as shown, and 12 is a flat reinforcing plate attached to the door, as illustrated.

As illustrated in Figs. 6 to 8 inclusive, 13 is the car door in general, 14 an opening between the two portions thereof, 15 is an integral flange on the forwardend of the door which is preferably deeper at its intermediate portions and tapers thence to the ends of the door, this forward flange serving as a stiffening member for thedoor. This forward flange 15 has an inwardly bent portion 16 adapted to further strengthen and stiffen it. The rear integral flanges of the door are 17 and it is also provided with integral side flanges, as shown, in fact, the entire door is provided with an integral continuous flange extending downwardly from all the edges thereof, the front flange being deeper and tapering as above described. 18 is the integral flanged edge of the door at its narrow-V est portion adjacent to the'opening 14, 19 is a pan-shaped brace either formed of pressed plates or a casting secured to the door, as illustrated, and provided with an opening to receive the clevis bolt 20, which is secured E thereto, as illustrated, for the purpose of attaching to the door operating mechanism.

' Referring now to Figs. 9 to 11 inclusive, 21 indicates another slightly modified form of door in general, provided with two end portions and a space or opening 22 between the same, 23 "isthe front flange portion formed integral with the door,fprojecting downwardly therefrom and of less depth at the ends than at the central portion, being provided with an integral flanged edge 24 which projects outwardly, as illustrated, to further stiffen the door, inaddition to which the'reinforcing angle 25 is secured to the intermediate portion thereof, as illustrated. This door is also provided with an integral flange extending around all the edges thereof, that at the narrowest portion being 26 and the rear flange 27. A brace 28, which may be either formed of pressed plates or a casting, is secured to the door, as illustrated, and provided with an opening to receive the clevis bolt 29, which is adapted to be secured to the door operating mech-' anism. 7

Referring now to Figs. 12 to 14 inclusive,

another slightly modified form of door is indicated generally as 30, 31 is the opening or.

space between the two portions thereof, the integral rear and end flanges are 32-, the integral deeper and tapering front flange edge is 33, provided with forwardly projecting integral portion 34, this door being provided with a pair of flanged stifleners 35 and 36, the latter being shorter than the former,

' both secured to the door plateand provided with a space between them at their intermediate portions, adapted to receive the clevis bolt 37 the nut ofwhich rests against the washer plate 38.

It will be seen fromthe foregoing that we provide a door made in one piece adapted to close a pair of twin hoppers, one on either side of the center sill of the car or otherwise and all margins of the door are provided with downwardly extending flanges formed may usesuch substitutions, modifications, or

equivalents thereof, as are embraced within the scope of our invention, or as pointed out in the claims. 7.

Having thus described our invention, what we a claim and desire to secure by Letters Patent is p v 1. A car drop door comprising a metal plate provided with an integral downwardly extending'flange on its edges, the intermediate portion being narrower than the end portions. Q 1 Y 2.
